Abstract
A delay circuit includes a primary circuit receiving an input signal and outputting two intermediate signals having a delay therebetween. A combination circuit with two modules that output a combination signal on the basis of the addition with weighting and effect of integration of the intermediate signals and of their conjugate. Each module includes a discharging circuit and a charging circuit, which each have switching elements controlling the connection between a common line and first and second supply potentials. These connections use a variable resistor and a non-variable resistor so as to ensure the permanent participation of the two modules in the charging or discharging of a capacitor. This delay circuit is particularly useful in CMOS circuits.
